Mean, m = 72

Step-by-step explanation:

It is given that, Carl earned grades of 62, 78, 59, and 89 on four math tests.

It is required to find the mean of his grades.

Mean of a data is given by :

$m=\dfrac{\text{sum of observations}}{\text{total no of observations}}$

Sum of observations is 62 + 78 + 59 + 89 = 288

Total no of observations are 4

So, mean of his grades is :

$m=\dfrac{288}{4}\\\\m=72$

So, the mean of his grades is 72.
